Desempenho de um sistema híbrido eólico-solar fotovoltaico autónomo operando com pequenas cargas

Abstract

Hybrid systems of energy conversion are those that make possible lhe combination of more than one source, for example: Wind, solar and diesel, and the optional utilization of systems for energy storage. They are systems for electricity generation which use renewable sources of energy, with minimum environmental impact, and represent an energetic contribution more and more significative, being relevant to know their details and behavior. Those systems present technical and economical viability to places that are far from the conventional electric distribution systems. This dissertation centralizes in the mounting, and installation of the photovoltaic part and in the experimental analysis from an Wind photovoltaic hybrid system of small port, with battery storage. The Wind photovoltaic hybrid system was assembled in the laboratory of special termic dispositive (LABDTE). The experimental hybrid system is composed by: One 750 W aero-generator, four photovoltaic paneis (80W each), four batteries of intense discharge with capacity of 105 Ah each one, two charge controllers, one to the Wind system and the other to the photovoltaic system; one convertor DC/AC; one ipiranometerl to measure the solar rays; one conch anemometer. The experimental data contained in this work made possible the analysis of the solar and Wind sources behavior, as well as allowed the calculation of the energy generated by the small port hybrid system used, and the determination of its performance.
